ok here is what i experienced and gathered information from testing and withnessing etc...
there are 2 (two) NEW WAYS of SOFTBANS
1)
the first new softban method, all pokemons will FLEE resulting in not beeing able to catch the pokemons!
however we will still be able to loot pokestops!
2)
this one was introduced a bit later! it will cause you not to be able to LOOT ANY POKESTOPS.
i think they improved their first idea by making you not able to loot any pokeballs, this way you wont be able to get ANY xp whatsoever and wont be able to catch pokemons since you will run out of pokeballs, unless you spent money in the shop which will only benefit them
HOWEVER at this point, the ban has NOT been lifted for any1 YET, we dont know if it will ever lift or if its permanent!
what we know is that they definately have certain ways to detect if you are doing some shady things
these 2 bans occur when you have a crazy bot setting like moving too fast
EDIT: FOR CLARIFICATION
there are also other ban OLD BANMETHODS
*) SOFT IP BAN, your ip is getting soft banned for roughly 1 hour, every login from that ip wont load map objectives like pokestops gyms or pokemons
*) SOFT account ban, happens when you traven too fast, pokemons will flee and you cant loot pokestops HOWEVER this one is bypassable with the 45/45 spin trick!!!
these old bans have nothing to do with the new ones!
